To all zii/10711. t 111mg/ concern.'

Be it known that T, Jnssn C. HOWARD, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Tmprovenients in Pumping Devices,

of which the following is a specification.

My invention relates to pumping devices and aims to provide a construction of pumping unit which may be utilized in a great many places, one very good example being in the rural districts where each individual house may be itself provided with a structure for giving running water wherever and whenever desired.

The essential object of my invention resides in the lubricating mechanism for n1aintaining certain of the pump parts in a thoroughly lubricated condition. This structure particularly takes the form of a hollow connecting rod structure and also a hollow bearing portion structure forming receptacles for the lubricant and a wick structure located within these receptacles to permit the proper flow of lubricant to the parts desired. 'Y

Figure 1 is a vertical longitudinal section taken. 'through a pump unit in which my improved structure is incorporated and also showing the driving motor and its connections, and y Fig. 2 is a transverse vertical section taken through my pumping unit and showing a housing within which any preferred type of switch structure may be confined for oontrolling the operation of the motor shown in Fig. 1. In these drawings, the entire mechanism is shown as being mounted upon supporting base 1 which is provided with a pair of upstanding standards 2 and 3 for supporting the bearing members in which the pump operating shaft 18 is journaled. This base is also provided with an electric motor 41 having an armature shaft 12 carrying a worm 13 at its outer end bymeans of which the proper pumping motion is derived. This worm is designed to mesh with a worm wheel 14 held confined within a casing or housing structure 15 of which the removable cap 16 forms a portion. It will be noted by particular reference to Fig. 1 that the side of the casing 15 opposite from that to which the cap 16 is applied is provided with an outwardly extending hearing portion 17 for rotatably receiving the shaft 18 upon which the worm wheel 1st is rigidly mounted. This bearing portion 17 is of a hollow nature and extends downwardly as is shown, the hollow portion 19 being' so arranged that a receptacle is :formed whichis designed to he filled with lubricating oil and this oil is in turn comnu'micated to the rotatable shaft 18 by means of the wick 2O which is held in contacting position with the shaft 18 by means of the coiled spring 21. The/extreme outer end of the bearing portion 17 is also provided with an annular groove 22 into which any excessive oil carried bythe shaft 18 is permitted to drop land which will then ultimately pass into the receptacle 19 through the small passage At this point, it may also be well to relate that T intend to pack the casing 15 with asuitable lubricating grease in order that the gears 13 and 14 may at all times be in a perfectly lubricated state.

The shaft 18 carries a plurality of ecceiry tric portions 24C the numbers of these ecceir trios .corresponding with the number of cylinders used and in the present instance, these eccentric portions are shown as being formed integral with the shaft .18. As illus# trated, one end ofthis shaft journaled in the outstanding bearing 17, while its opposite end is jouriialed in a similarly formed bearing 25'carried b v the upper end of a bearing support 2G, this latter bearing support being formed similarly inall essential respects as the bearing support for the bearing portion 17.

Tn'the present case, l have shown three cylinders, these cylinders being designated 27 and each cylinder being provided with an A inlet valve 28 and an outletvalve 29. These valves are carried in valve chambers 80 and 31 respectively and are held in close engagement with their valve seats by coiled springs 82 held coniin'ed in caps 33. Each of the valves 28 and 29 is in communication with the respective cylinders by means of passages 84 and 35 and all of the valve casings on the inlet side as well as. on the outlet side, are in communication with each other so that a single inlet pipe 36 and a single outlet pipe 37 may be used. Y This outlet pipe 37 leads to a tank or other place of storage for use, while the small pipe shown at 38 is in communication with the Outlet chambers, but leads to an automatic switch located upon the base 52 and confined within the housing 51. This switch forms no part of the present invention. A piston 39 is movable up and down within each cylinder and in order that the proper suction may b e had, each of these cylinders is formed with an' enlarged portion 40 at its upper end. l/V ithin this enlarged portion lvvplace a series oi gaskets 4ta-nd 42, the gasket 4l being held in positionby means of the member shown at 43, while the gasket 42 and, in fact, the

io gasket structure as a whole, is held in position by means oi theV bushing 44 having threaded engagement withthe enlarged portion 40 oteach ot the cylinders, as shown. By tightening or loosening this bushing 44,

i5 the gaskets may be squeezed into firmer or looser engagement with the corresponding pistons 39, as may be desired. Each of these pistons is also prei'erably iorined hollow, as is shown, and the arrangement is such that they are vertically disposed so that they may form oil receptacles. lflachy piston is also provided with a cross head 45 to serveas a vmeans of pivotal connection with the piston rod 46, each of these piston rods being` also formed hollow from their point of pivotal connection to the eccentric structure and leach being further provided with apertures '47 adjacent the point of pivotal connection, in order to permit the imiow of oil 'from the oil receptacle termed by the hollow piston.

'-40 the eceentrics which it is` desired to keep thoroughly lubricated by means of the wick structure just described.

From the pump structure described, it will be apparent that rotation of the shaft 18 will cause a continuous reciprocation of the pistons ii'fitlril their cylinders. This reg ciprocation will cause an inflow of water into the cylinder and also an outiiow through the pipe 37. During the operation ot the pump, the parts are maintained in a thoroughly lubricated condition so long as suiiicient oil remains in the oil receptacles. This oil is ted to the bearing parts by means ot the wicks shown and these wicks are held in po* sition .by means of their respective springs. rl'his Jr'eatnre l deeni particularly valuable.

rWhat l claim, is:

l. ln a pumping unit, a vertically di."- poscd cylinder, a'hcllow piston movable in said cylinder, a hollow piston rod pivotally connected with said piston and extending out tl rough the top side of said cylinder, said piston rod having an aperture adjacent said pivotal connection, an eccentric iior the op-v posite end ot said piston rod, and a spring pressure wick structure within said hollow piston to transiter oil from said pivotal connection to said eccentric.

Zln lubricating mechanisn'i for pumping units, the combination with a vertically disposed cylinder having a reciprocating piston mounted therein, of an eccentric carrying driven shaft, a hollow connecting rod cooperative with said shaft, a piston for effecting the reciprocation of the latter, a wick positioned in a lubricant containing chamber tormedin said rod, and resilient means for Jr'orcing said wick into engagement with the shaft eccentric.

ln testimony whereof l my signature in presence of two witnesses. Y

JESSE C. HOWARD.
